Hello again Sylvain
I kept looking for the <fd:message> widget you mentioned, and couldn't
find any reference to it in the docs.
Do you actually mean the <fd:output widget ?
Thank you
Elad

You can add a <fd:validation> on any widget, including a form. But not every
widget can hold validation errors, as not every widget has a visual
representation.
So validation on non-visual widgets should set validation errors on one of
their child widgets. Another option if there's no suitable widget to attach the
error to is to add the error text to a <fd:message> widget.
For more details, see the javadocs of
o.a.c.forms.validation.WidgetValidator and form1.xml in the samples: the
"contacts" repeater has a validator that checks row uniqueness and sets an
error on the duplicate rows.

That should occur automatically.
Hope this helps,
Sylvain
